This is a Vector data set. It contains the following vector data types (SDTS terminology):
Planar coordinates are encoded using coordinate pair
Abscissae (x-coordinates) are specified to the nearest not determined
Ordinates (y-coordinates) are specified to the nearest not determined
Planar coordinates are specified in METERS
The horizontal datum used is North American Datum of 1927.
The ellipsoid used is Clarke 1866.
The semi-major axis of the ellipsoid used is 6378206.4.
The flattening of the ellipsoid used is 1/294.98.

This dataset was developed to provide a geologic map GIS of Spokane County for use in future spatial analysis by a variety of users. These data will better enable Spokane County agencies to predict the likely occurrence of additional mineral lands, primarily containing sand, gravel, rock and clay deposits.
This database is not meant to be used or displayed at any scale larger than 1:100,000 (e.g., 1:62,500 or 1:24,000).

Attribute accuracy was verified by manual comparison
of the source with hard copy printouts and plots.
The horizontal positional accuracy for the digital data is
probably no better than +/- 70 meters.
It was tested by visual comparison of the source with hard copy
plots.
This dataset was produced from previously published reports
(Carrara and others, 1995; Derkey and others, 1998; Johnson
and Derkey, 1998; Joseph, 1990; Kiver and others, 1979; and
Waggoner, 1990a, b) and from unpublished field mapping by
Miller (written communication, 1995). These sources are
considered to be the best geologic maps available for the
area at a scale of 1:100,000.
Polygon and chain-node topology present.
Polygons intersecting the neatline are closed along the border.
Segments making up the outer and inner boundaries of a poygon
tie end-to-end to completely enclose the area. Line segments are
a set of sequentially numbered coordinate pairs. No duplicate
features exist nor duplicate points in a data string. Intersecting
lines are separated into individual line segments at the point of
intersection. Point data are represented by two sets of coordinate
pairs, each with the same coordinate values. All nodes are
represented by a single coordinate pair which indicates the beginning
or end of a line segment. The neatline was generated by
mathematically generating the four sides of the quadrangle,
densifying the lines of latitude and projecting the file to UTM
zone 11 (with a y-shift).
Are there legal restrictions on access or use of the data?

Any hardcopies utilizing these data sets shall clearly indicate their source. If the user has modified the data in any way they are obligated to describe the types of modifications they have performed on the hardcopy map. User specifically agrees not to misrepresent these data sets, nor to imply that changes they made were approved by the U.S. Geological Survey.
